SPECIFICATION forming part of Letters Patent NO. 611,248, datedSeptember 27, 1898.

Application'filecl October 30,1897. Serial No. 656,918. (No model.)

To all whom it may concern:

Be it known that we, JAMES C. GRAY and THOMAS RODERICK, citizens of theUnited States, residing at Columbus, in the county of Franklin and Stateof Ohio, have invented certain new and useful Improvements in Gas-Burners; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. a The objectof our present invention is to provide an improved burner for eitherartificial or natural gas.

In the annexed drawings, illustrating embodiments of our improvements,Figure lis a front view of a burner in position ina heater. Fig. 2 is alongitudinal vertical sectional view of the left-hand side of the burnershown in Fig. 1. Fig. 3 is a transverse vertical sectional View taken ona plan indicated by the line w m, Fig. 2; and Fig. 4 is an end View.

The burner proper is preferably made up of two or more sections Z and Z,of different lengths and arranged in a line parallel,or substantiallyso, with the supply-pipe, so that by combining those of equal and ofdifferent lengths a great variety of sizes of burner may be made. Forexample, if the several sections are five and six inches in length aburner having a total length of ten inches, eleven inches, twelveinches, fifteen inches, sixteen inches, 850., may be had by permutationof the two sizes of casting. The sections consist of a horizontaltubular portion a, having jet-holes a, and a vertical inlet or mixingtube a opening into the portion a. To avoid expense and trouble ofcoring in the manufacture of these parts, each section is made of twocorresponding parts by division vertically, that are matched andfastened together by means of screws or bolts 1) b to form the tubularportion andthe jet-holes.

Downwardly-extended end pieces or legs 0 are placed against the ends ofthe burner and a bolt 01 passed entirely through the horizontal tubularportion of the burner; A nut turned up tightly on the bolt will securethe sections of the burner and the end pieces of the legs together. Toprevent the escape of gas at any place except through the j et-holes,asbestos or other packing, as shown at e, may be provided between thejoints. The lower ends of the end pieces or legs are bifurcated orslotted, as shown at c, to receive the su ply-pipe f, having smallescape-holes f, and on .the pipe are collars g, having upwardlyextendingslotted arms gf. A stationary bolt or pink in the leg 0 extends throughthe slot of each of the arms 9, which are clamped to the legs by meansof nuts 71,. Upon loosen ing these nuts the pipe may be raised orlowered to diminish or increase the distance of the supply-pipe from theburner proper.

In feedingtheburner with gas from the holes f in the supply-pipe the jetof gas takes along with it more or less air, according to the pressureor velocity with which it escapes, and the combustion of thegas is moreor less perfect, according to the quantity of air mixed with it.Therefore by making the supplypipe adjustable with respect to theburner, or vice versa, the quantity of air to be taken .in or mixedmaybe nicely regulated.

- The burner maybe fastened to the heater by means of boltsz', passingthrough'the legs :or end pieces and the sides of the heater, withnuts 1) for fastening the burner to the ends of the heater.

The shanks of the screw 1) in the vertical mixing-tube a assist inmixing the gas and air, and thebolt din the burner-tube serves to spreadthe gas to the various jets, insuring complete combustion and largevolume or area of flame.

What we claim, and desire to secure byLetters Patent, is-

A gas-burner constructed of two or more sections each of which is madeof corresponding or matching halves, to form the horizontal tubel havingjet holes a and mixing inlettube a bolts 19 uniting the said matchinghalves, bolt 1) passing through the inlet-tube a and serving to mix theentrained gas and air, and the bolt 61 uniting the several sections andserving to spread the gas at the jetholes, substantially as shown anddescribed. In witness whereof we have hereunto affixed our hands each inthe presence of the two here subscribed witnesses.
